Abstract:
A driving apparatus includes: a driving section configured to drive a control terminal of a semiconductor device according to a control signal input from an outside, the semiconductor device including a first main terminal, a second main terminal, and the control terminal that is configured to control a connection state between the first main terminal and the second main terminal that are connected in parallel with a snubber; and a drive control section configured to lower a drive capability of the driving section during a period in which an inter-main-terminal voltage between the first main terminal and the second main terminal changes by a predetermined reference voltage difference owing to switching of the semiconductor device, compared with other at least some periods.
